You have bought a pack F, so you have received :
- One PCB with all electronic components already soldered, GRBL already installed. The shield has been tested on my own K40 with my motorized bed.
- Few jumpers to change microsteps resolution if you want (they are under the drivers)
It’s very important to follow carefully the chapter “Installation in K40” in this article : link
Then you’ll have to install & configure Lightburn : link
After that, you will have to follow the steps for the first use in the K40 : link
In particular, if you DON’T have a motorized bed, please deactivate the homing of Z axis (instructions in the same article)
Finally, you’ll be able to connect your ESP32 to your wifi network following instructions here : Link
Please take the time to read all instructions to avoid damaging your K40 or your new shield 🙂
Thank you very much again !
